I HAVE THE SAME PROBLEM ON MY PC.
On my phone and ipad, they are working fine, but on PC, it was running ok , until a windows update took place, then it's not recognised as registered device again, I contacted their support and they don't even understand what the problem is and told me it's due to max registered device reached, and they are just plain dumb. IMO this is a software fault on astro side , since they cannot uniquely identify a pc/laptop when they are registered/deregistered. If they don't fix it, then only way is to rely on iphone/ipad. Perhaps it's a tactic from them to discourage us to use on lappy. Fok them.

No. Problem will reappear do no point wasting the ‘credit’.
Ended up using bluestack to run it and works.
